Title: A machine for dyeing wool, yarn, cloth and the like
IPC: D06B5/00
Filed: 1952-09-16
Abstract: <PICT:0727430/IV (c)/1> In a dyeing apparatus in which the dye liquor is circulated through the material alternately in forward and reverse directions, the propeller which promotes the liquor flow is housed in a casing separate from but in communication with the container in which the material is treated.  The Figure shows a dyeing apparatus in which the material to be dyed is placed in a container 24 formed between two perforated plates 18, 21 which are housed in a vessel 10 which communicates via tapered passages 13, 14 with a propeller chamber 11.  The propeller 15 is rotated in alternate directions by the reversible electric motor 17 and the capacity of the container 24 may be varied by sliding the upper perforated plate 21 to which a tube 20 is attached on rod 19, the rod and tube being provided with through apertures 191, 23 so that the rod 19 may be held in a given position by means of a rod 25 passing through an aperture 23 and engaging with apertures 22 in the wall of the tank 10.  The dye liquor may be heated for example, by admitting steam via pipe 26.  In a modification the perforated plates 18, 21 21 are supported at their sides, each plate being carried on two uprights on opposite sides of the plate.

Title: Apparatus for pumping liquids from storage containers or the like
IPC: F04D9/00
Filed: 1957-07-23
Abstract: 864,620. Centrifugal pumps. CIBA Ltd. July 23, 1957 [July 27, 1956], No. 23307/57. Class 110 (1). A submersible centrifugal pump 26 is contained in a vessel 13, and a suction pipe 31 extends downwardly from a point near the upper wall of the vessel above the level of the pump and above the level of a shaft bearing 24, which is thus lubricated by the liquid being pumped. A delivery pipe 28 connected tangentially to the pump casing is continued outside the vessel 13 by a pipe 20. During operation of the pump, the vessel 13 is full of liquid. When the pump is stopped, liquid flows back from the pipe 20 to keep the vessel 13 charged with liquid. If the pipe 20 is not of sufficient volume for this purpose, it can be connected to a receptacle of sufficient capacity. When the air within the pipe 20 reaches a small opening 29, the air passes to a dome 30 above the suction pipe 31 and interrupts the siphoning of liquid from the vessel 13. An extension 18 of the suction pipe extends towards the bottom of the container (not shown) from which the liquid is being pumped. The vessel 13 may be arranged within the container, being suspended from the underside of the top cover of the container by means of the pipe 20 and a tubular enclosure 21 for the driving-shaft 16. The driving-motor and an upper bearing for the shaft 16 are mounted above the top cover. Alternatively, the vessel 13 may be mounted above the container.

A method of manufacturing structural members from metal blanks includes the step of bending at least two elements of a blank simultaneously through different angles so that the horizontal projections of the most displaced part of each element are equal during each stage of the forming process. In the formation of a Z-shaped structural member the blank 1 is first bent about an axis O by a cold roll forming machine (not shown) to form elements n, h and m (Fig. I) by bending stages 2, 3 and 4 such that the horizontal projections a 1 , a 2 , a 3  of the extremities of each element between each bending stage are equal. Secondly the element n, his bent in a roll stand about an axis O 1  (Fig. 2) to . form elements n and h of the Z-shaped member and simultaneously forming the final angle between elements h and m. The horizontal projections b 1 , b 2 , b 3  of the extremities of each element n and h between each bending stage are also equal. In forming an unequal-flange channel guider (Fig. 4) the blank is progressively bent to form elements R, S, P such that the horizontal projections d 1  to d 5  are equal at each bending stage. In another embodiment an L-shaped girder is formed by the above method.

Title: Apparatus for controlling the rate of deposition of an evaporated material
IPC: G05B1/08
Filed: 1961-07-03
Abstract: 964,343. Automatic control of deposition rate. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 3,1961 [July 21, 1960], No. 23878/61. Heading G3R. The rate of deposition of an evaporated material on a substrate is controlled by causing the substrate to vibrate at its natural frequency which is compared with a reference frequency to derive a difference frequency which is converted into pulses representative of the amount of deposition. As shown, a crystal 1a, upon which material is being deposited, controls the frequency of an oscillator 1 and a reference crystal 2a controls the frequency of an oscillator 2. The difference between the frequencies is determined in a mixer 3 and fed through a low-pass filter 4 to a trigger circuit 5 from which a sequence of single pulses is fed to a gate circuit 6 operated by a control unit 10. The gate circuit is opened by the control unit for two successive, equally long intervals so that two pulse sequences are fed to a counter 7 which accumulates the pulses positively or negatively under the control of the control unit 10 so that one pulse sequence is subtracted from the other to drive a total count which is a measure of the rate of deposition of the evaporated material. During a third time interval a reference rate,defined as a sequence of single pulses, is fed to the counter 7 from a counter 8 controlled by the control unit 10 to derive a final count which represents the deviation of the measured rate of deposition from a desired rate. After the determination of the deviation, the counter 7 is reset to zero, during the third time interval, by step-by-step backward counting, and at the same time'a single pulse of a length corresponding to the duration of the resetting process, or a corresponding pulse train, is fed via line 17 to a gate 9 to open the gate to pass a number of pulses of fixed frequency representative by the deviation from the control unit 10 to a device 11 controlling the evaporation process.

By mounting valve 58 on the carburetter body the passage 56 is reduced in length and the response time to correct mixture ratio errors is reduced, so that a three-way catalyst in an exhaust gas reactor downstream of sensor 30 operates at maximum efficiency. Valve 58 includes a valve-member 58g supported by flexible member 58h and actuated by the valve solenoid, and a valve seat 58c which may be mounted separately in the carburetter body or may be an integral part of the valve. The valve may admit additional air to the main fuel supply passage, as shown, or to the slow-running fuel supply passage.

Abstract: 828,161. Reciprocating pumps. DOWTY EQUIPMENT Ltd. Aug. 6, 1957 [Aug. 7, 1956], No. 24198/56. Class 102(1). [Also in Group XXIX] In a pump of the type described in Specification 678,470 the flow control valve 25 comprises a piston 26 subjected to the output pressure of the pump 18 through a passage 28, the head of which engages a piston 63 slidable in a chamber 62 in a valve spool 60. A restricted passage 64 interconnects the end faces of the piston. A push rod 65 engages the end of the piston 63 and engages a member 66 loaded by a spring 29. A light spring 69 engages the member 66 and the spool 60. The spool is provided with a recess 72 having a tapered edge which controls flow from a port 49, connected to the outlet of the pump 15, into the recess and so to the open port 50 connected to the inlet of pump 18. A slow rise in output pressure of the pump 18 above a predetermined pressure slowly raises the piston 26 so that oil flows from one side of piston 63 to the other until the piston 63 engages and lifts the spool 60 whereby communication between the port 49 and the recess 72 is closed. Sudden rises of output pressure does not permit flow through the passage 64 and the spool valve is immediately actuated. Further rise in pressure lifts the piston 26 sufficiently to connect passage 28 to passages 76 and exhaust. The end of the piston 26 is provided with a dash-pot piston 57.
